Rhino, Nashorn IdPV2 and Scripting

[Cantor, Scott]

Since the jars here can basically be named anything, I suggest we rename
them to something we can understand later.

I assume js.jar is the rhino implementation, and js-engine is the adapter
that makes it a scripting engine?

I'm not clear on how the JDK version is a factor, is it that you targeted
JDK8 with the compile so it doesn't run on JDK6?

Do we just want to do a version built with JDK6 that will run on any of
them?
